SMA Female 4-Hole Flange Mount RF Connector – Solder Attachment, 8.63mm Hole Spacing, 1.27mm Pin Diameter, Stub Terminal

SMA Female 4-Hole Flange Mount RF Connector – Solder Attachment, Model SMA-KSS8

The SMA female 4-hole flange mount RF connector with 1.27 mm pin diameter and 8.63 mm hole spacing is a high-precision solution for robust solder attachment in high-frequency RF systems. Operating from DC to 18 GHz with 50 Ω impedance, the SMA-KSS8 delivers consistent performance in demanding test and communication environments.

Outstanding Electrical Performance

Engineered for precision, the SMA-KSS8 RF connector offers VSWR ≤ 1.08 and insertion loss ≤ 0.06 √F(GHz) dB. This ensures stable impedance matching, low signal loss, and excellent return loss across the full operating band—ideal for laboratory instruments, radar systems, and satellite communication hardware.

Durable Material Construction

Made from corrosion-resistant passivated stainless steel with gold-plated beryllium copper contacts, the SMA-KSS8 connector provides excellent mechanical strength and superior electrical conductivity. All materials are fully RoHS and REACH compliant, ensuring long-term reliability under repeated mating cycles.

Mounting Configuration and Use

The 4-hole flange mount design allows secure panel installation while the solder attachment ensures firm mechanical integrity. The connector’s stub terminal simplifies soldering while maintaining high-frequency stability in RF modules, amplifiers, and precision test fixtures.
